Appellant is not advancing final arguments

my petition under HMA sec. 11 r/w sec 5 (i) allowed.

marriage declared null & void.

wife failed to prove that her earlier marriage was dissolved as per custom.

she filed appeal.

R&P, paperbook etc. formalities completed.

the case is for final hearing.

Bombay HC directed the District court to conclude the appeal as per sec. 21 B.

appellant is NOT ADVANCING FINAL ARGUMENTS

all the time they keep telling this / that reason to delay the case.

kindly suggest remedy.
